Scope and content
This instrument was used for angular measurements of the highest accuracy and astronomic-geodetic observations, providing a high resolving power and brilliant image, at 60x and 80x magnification. Its specific applications included: First Order Triangulation; Primary Control by Distances; Geographical Determinations (azimuth, latitude, longitude); Determination of the Deviation of the Vertical by Astronomical Observations; and as a Stationary Instrument in Observatories. Manufactured by the Wild Heerbrugg Ltd. company of Switzerland (Dr. Heinrich Wild brought his revolutionary ideas into the scope of astronomic-geodetic measurements), the Wild T4 was purchased by Ryerson’s Civil Engineering Department around 1968.
